a The source for the traditional income in this column is the portion of the 2014 CPS ASEC sample (about 68,000 households) that received a set of income questions similar to those used in 2013. The 2014 CPS ASEC included redesigned questions for income that were implemented to a subsample of the 98,000 addresses using a probability split panel design.

b The source for the redesigned income in this column is the portion of the 2014 CPS ASEC sample (about 30,000 households) that received the redesigned income questions. The 2014 CPS ASEC included redesigned questions for income that were implemented to a subsample of the 98,000 addresses using a probability split panel design. The redesigned income questions were used for the entire 2015 CPS ASEC sample.

NOTE: Estimates refer to all children ages 0–17. The table shows income categories derived from the ratio of a family’s income to the family’s poverty threshold. In 2014, the poverty threshold for a family of four with two children was $24,008. For example, a family of four with two children would be living below 50 percent of the poverty threshold if their income was less than $12,004 (50 percent of $24,008). If the same family's income was at least $24,008 but less than $48,016, the family would be living at 100–199 percent of the poverty threshold. Data for 2010 used the Census 2010-based population controls. The 2004 data have been revised to reflect a correction to the weights in the 2005 Annual Social and Economic Supplement (ASEC). Data for 1999, 2000, and 2001 use Census 2000 population controls. Data for 2000 onward are from the expanded Current Population Survey (CPS) sample.
